Overview

Aim:
The aim of our study is a retrospective review of non‑pharmacological treatment of the most commonly occurring regular supraventricular tachycardias with an emphasis on safety and effectiveness.

Methods:
We included the data of all our consecutive patients diagnosed with an accessory pathway (AP) and/ or AV reentry tachycardia (AVRT), AV nodal reentry tachycardia (AVNRT) and typical atrial flutter (AFL), who were treated in our centre using radiofrequency catheter ablation (RFA) between 2008 and 2012.

Results:
In total, we conducted 1,168 ablations, comprising 141 procedures for AVRT/ AP, 383 procedures for AVNRT and 644 procedures for AFL. The acute success rate was 98.1% for AVRT/ AP, 98.6% for AVNRT and 99.8% for AFL. The incidence of complications was 1.03% in all procedures. Success and complication rates in our centre are consistent, and often more favourable in comparison with the literature.

Conclusion:
In patients with SVT, RF catheter ablation is a highly effective and safe method.
